Salaam,
Hey, plz take a look at it......its amazing!!!!!!

In 1870, Eliza Murfey
patented 16 devices for improving the packing of journals and bearings for railroad-car axles. These packings were used to lubricate the axles with oil which reduced derailments caused by seized axles and bearings.

In 1879, Mary Walton
developed a method of deflecting smoke stack emissions through water tanks and later adapted the system for use on locomotives. In the 1880s, many cities developed a mass transit system using noisy elevated trains. To reduce the noise, Walton invented a sound-dampening system that cradled the track in a wooden box lined with cotton and then filled with sand. She received a patent for the system on February 8, 1881, and later sold the rights to the Metropolitan Railroad of New York City. Other inventions by women included a railway crossing gate by Mary I. Riggin and several patents for the construction of railway tracks by Catherine L. Gibbon.

In 1809, Mary Dixon Kies
received the first U. S. patent issued to a woman. Kies, a Connecticut native, invented a process for weaving straw with silk or thread.

In 1845, Sarah Mather
received a patent for the invention of a submarine telescope and lamp. This was a remarkable device that permitted sea-going vessels to survey the depths of the ocean.

Martha J. Coston
perfected then patented her deceased husband’s idea for a pyrotechnic flare. Coston’s husband, a former naval scientist, died leaving behind only a rough sketch in a diary of plans for the flares. Martha developed the idea into an elaborate system of flares called Night Signals that allowed ships to communicate messages nocturnally. The U. S. Navy bought the patent rights to the flares. Coston’s flares served as the basis of a system of communication that helped to save lives and to win battles. Martha credited her late husband with the first patent for the flares, but in 1871 she received a patent for an improvement exclusively her own.

Margaret Knight
was born in 1838. She received her first patent at the age of 30, but inventing was always part of her life. Margaret or ‘Mattie’ as she was called in her childhood, made sleds and kites for her brothers while growing up in Maine. When she was just 12 years old, she had an idea for a stop-motion device that could be used in textile mills to shut down machinery, preventing workers from being injured. Knight eventually received some 26 patents. Her machine that made flat-bottomed paper bags is still used to this very day!

Ann Moore
was a Peace Corps volunteer, she observed mothers in French West Africa carrying their babies securely on their backs. She admired the bonding between the African mother and child, and wanted the same closeness when she returned home and had her own baby. Moore and her mother designed a carrier for Moore’s daughter similar to those she saw in Togo. Ann Moore and her husband formed a company to make and market the carrier, called the Snugli (patented in 1969). Today babies all over the world are being carried close to their mothers and fathers.
